Lanthanum is often placed in the d-block of the Periodic Table because it is the first element in the f-block series, specifically the lanthanides, but it exhibits a configuration that allows it to be associated with d-block elements. Its electron configuration ends with 5d¹, meaning it has an electron in the 5d subshell, which is characteristic of d-block elements. Furthermore, it can form similar bonding and oxidation states as transition metals, justifying its placement alongside them in certain contexts. However, it is technically classified as an f-block element due to its role in the lanthanide series.

What is lanthanum named after?
Lanthanum is named after the Greek word "lanthanein," which means "to lie hidden." This is because lanthanum was initially difficult to separate from other rare earth elements.
Where does lanthanum come from?
Lanthanum is primarily obtained from minerals such as monazite and bastnäsite, which are found in rare earth element deposits. These minerals contain significant amounts of lanthanum along with other rare earth elements. The extraction process typically involves crushing the ore, followed by chemical separation techniques to isolate lanthanum from other elements. Major producers of lanthanum include countries like China, the United States, and Australia.
